Copper Tungsten Sheeting
Using our extensive experience in metallurgy and proprietary copper infiltration technology, WEISON can manufacture tungsten copper sheets of various thicknesses and dimensions. The resultant product has excellent resistance to mechanical wear and electrical erosion together with complying with international quality standards.
Tungsten-Copper alloy is a two-element alloy mainly based on tungsten and supplemented by copper. It is a composite metal material. As metal copper and metal tungsten have a large difference in physical properties, it’s impossible to adopt casting process for production. Now the industry generally uses copper infiltration technology for production. Our infiltration copper technology is of the mostly historical research and skillful manufacturing experience in China.
